1. Compatibility: The cordless welding station is applicable to for interface batteries(excluding batteries). This portable welding station can help you complete welding work more conveniently and quickly. 2. Fast Heating & Adjustable Temperature: This electric HD digital welding station has fast heating speed. The temperature reading is displayed on the digital display, and the temperature can be set accurately by easily turning the adjusting knob. 3. Safety in Use: Digital solder iron station kit is made of materials with built-in low-voltage protection. In the automatic cooling mode, when not in use, put the handle on the handle frame, the machine automatically cool, and the temperature rise when picked up. 4. cordless, easy to carry. Basic operation: 1: In normal mode, briefly press the encoder to enter the preset temperature mode (preset four groups of common temperatures according to your own needs, and rotate the encoder to cycle between these four groups of preset temperatures), and then press the encoder again to enter the preset temperature mode. Each time the encoder is rotated, the temperature increases by 10 degrees, and temperature is adjustable! 2: In normal mode, long press the encoder to enter the setting menu, short press to select, short press again to cancel the selection, long press the encoder in the menu interface to exit and return to the previous level!
